when I get a chance I am going to form some straigtend out 30-06 brass in my 444 marlin dies then cut it down to a length that will fit in a AK mag. I am thinking that with the taper making the OD larger the shorter the case gets ,that a .45 bullet could be used instead of a .44?? if this would work then perhaps 444 marlin dies could at least be used to do the forming. I am also thinking a .41 bullet would work good in cut down 30-06 brass. this would give better bullet weight to case capacity and a shoulder to head space on. there are several wild cats based on necked down 444 marlin brass. The .375 & .411 JDJ and the.375 EXPRESS (WATERS) are all made from necked down 444 Marlin brass. I think cut down 30-06 brass can be formed to make a rimless version of these. A shorter version that would fit a AK/AR mag would be a great round IMOA.
I got a new computer and hope to be able to post pictures soon of some prototypes im working on as well
